Premium Electric Coffee Grinder for Fresh Ground Beans - Fast & Quiet Burr Mill with Adjustable Coarseness - Perfect for Espresso, French Press & Drip Coffee Makers - Ideal for Home, Office & Travel Use

This is meant to grind coffee beans. That's not what I used it for. I used it to make eggshell powder out of cleaned and dried eggshells, to add to the soft food I was feeding my ferret to help him get accustomed to chewing bones. Now, I'm glad to say, he eats whole mice and quails without issue and even enjoys a whole raw eggshell from time to time. I will say that this product worked exactly as I needed it to, so if you need to grind up some cleaned and dried eggshells into a fine powder to add to a meat mixture for your pet ferret, I'd strongly recommend it. The rest of you coffee drinkers, good luck to you.
